201217042 六、發明說明： 【發明所屬之技術領域】 本發明係有關一種有機溶劑淨化裝置，尤指一種將製 程所產生含有有機溶劑之待淨化廢氣，先藉冰水將廢氣氣 流中之微粒濾除乾淨且除濕，然後經熱交換器適度加熱 後，再由活性碳吸脫附裝置進行吸附程序之設計者。 【先前技術】 按，生活和生産中廣泛應用的有機溶劑，在室溫下就 極易揮發成氣體，故又名揮發性有機物（Volatile Organic Compounds，VOCs)，而多數的VOCs對人體有一定毒性，必 須加以處理；然而，對於製程（諸如喷塗製程）所揮發產生 之VOCs廢氣，通常係如第一圖所示，先藉一活性碳吸脫附 裝置（10)對VOCs廢氣進行吸附與濃縮脫附之程序，再由一 淨化裝置（20)對濃縮之VOCs進行焚化或回收之淨化處理。 次按，活性碳之吸附性能如第二圖所示，其對VOCs之 吸附能力恰與吸水能力相反，相對濕度低時，對VOCs之吸 附能力高而吸水能力差，相對濕度高時，則吸水能力高而 對VOCs之吸附能力差，且其吸附性能在相對濕度50〜60 %RH之過渡區間會急遽轉變；故前述習知有機溶劑淨化裝 置，在廢氣氣流進入該活性碳吸脫附裝置（10)之際，因廢 氣氣流之相對濕度易受到天候之影響而變化，致使該活性 碳吸脫附裝置（10)吸附VOCs之能力呈現不穩定之狀態，亦 即整體之淨化成效不穩定。 再按，廢氣氣流中通常會存在有濾網所無法濾除之微 201217042 粒，而此等微粒乃會堵塞住活性碳之孔洞，降低活性碳之 吸附此力，且一旦微粒堵塞於活性碳之孔洞後就難以去 除，活性碳之使用壽命遂因此縮短。 【發明内容】 本發明之主要目的，係欲解決先前技術易受到天候影 響而淨化成效不穩定之問題，而具有淨化成效穩定不受天 候影響之功效。 本發明之另一目的，則具有延長活性碳使用壽命之功 效。 本發明之又一目的，乃具有節能之功效。 為達上述功效，本發明之結構特徵，係將製程所產生 含有有機溶劑之待淨化廢氣導入一活性碳吸脫附裝置，並 於該活性碳吸脫附裝置之下游端設置一淨化裝置，另於該 活性碳吸脫附裝置之上游端設置一用以升溫之熱交換器 者。 此外，進一步於該熱交換器之上游端設置一洗滌器。 又，進一步設置一冷卻器讓該洗滌器之洗滌水冷卻。另， • 進—步設置一熱泵連結該熱交換器與該冷卻器，讓該熱交 換器與該冷卻器分別與該熱泵之冷凝器與蒸發器進行熱交 換。 再者，該熱交換器進一步藉由一控制器調節升溫程 度，而該控制器乃根據待淨化廢氣之與相對濕度（或露點溫 度）調節該熱交換器之升溫程度。又，該熱交換器致使導入 該活性碳吸脫附裝置之待淨化廢氣之相對濕度維持在6〇% RH以下。另，該活性碳吸脫附裝置為活性碳流體化式濃縮 201217042 旨或固^床式濃縮器。再者，該淨化裝置為焚化爐、冷凝 器、噴霧室或喷霧加臭氧室。 【實施方式】 首先，凊參閱第三圖所示，本發明之第一實施例，係 ㈣程所產生含有有機溶劑之待淨化廢氣導人-活性碳吸 脫附裝置（ίο)，俾以對待淨化廢氣中之有機溶劑進行吸附 與濃縮脫附之程序，而該活性碳吸脫附裝置（1〇)可為活性 碳流體化式濃縮器或固定床式濃縮器；再於該活性碳吸脫 附裝置（10)之下游端設置一淨化裝置（20)，進而對藉由該 活性碳吸脫附裝置（丨〇 )濃縮脫附出來之有機溶劑，進行焚 化爐焚化或冷凝器回收之淨化處理；另於該活性碳吸脫附 裝置（10)之上游端設置一用以升溫之熱交換器（3〇)，俾以 將導入該活性碳吸脫附裝置（10)之待淨化廢氣適度加熱， 而查閱濕度表可清楚得知，升溫之結果會致使相對濕度下 降’亦即該熱交換器（30)之設置可提升該活性碳吸脫附裝 置（10)對有機溶劑之吸附能力。 此外，該熱交換器（30)進一步藉由一控制器（31)調節 • 升溫程度’而該控制器（31)乃根據待淨化廢氣之溫度與相 對濕度（或露點溫度）調節該熱交換器（3〇)之升溫程度，俾 使導入該活性碳吸脫附裝置（1〇)之待淨化廢氣，其相對濕 度得以維持在60%RH以下。 再者，請參閱第四圖所示，本發明之第二實施例係較 第一實施例增設一洗滌器（40)，該洗滌器（40)設置於該熱 交換器（30)之上游端，用以將廢氣氣流中之微粒濾除乾 淨；然而，若進一步設置一冷卻器（41)讓洗滌水冷卻，該 201217042 洗滌器（40 )則另可降低廢氣氣流之露點溫度，進而產生除 濕之效果；因此，由於該熱交換器（3〇)必須消耗熱能，而 該冷卻器（41)必須散發熱能，故利用一熱泵（50)連結該熱 交換器（30)與該冷卻器（41)，讓該熱交換器（30)與該冷卻 器（41)分別與該熱泵（5〇)之冷凝器與蒸發器進行熱交換， 俾將該冷卻器（41)所必須散發之熱能轉換成該熱交換器 (30)所必須消耗之熱能，進而節能；而該熱泵（5〇)之運轉 狀態及組成結構非為本案之專利標的，不再贅述。 基於如是之構成，本發明針對製程所產生含有有機溶 # 劑之待淨化廢氣，先藉該洗滌器（4〇)將廢氣氣流中之微粒 濾除乾淨，且若使用冰水洗滌則可先行除濕，再由該熱交 換器（30)適度加熱（通常不超過45。〇，俾使其相對濕度得 以維持在60%RH以下，讓該活性碳吸脫附裝置（1〇)在活性 碳吸附能力較佳之環境中進行吸附程序，乃不會受到天候 影響而造成淨化成效不穩定，且降低微粒堵塞活性碳孔洞 之可忐性，疋以，本發明具有淨化成效穩定不受天候影響 以及延長活性碳使用壽命之功效。 • 綜上所述，本發明所揭示之技術手段，確具「新穎性」、 進步性」及可供產業利用」等發明專利要件，祈請鈞 局惠賜專利，以勵發明，無任德感。 惟，上述所揭露之圖式、說明，僅為本發明之較佳實 施例，大凡熟悉此項技藝人士，依本案精神範疇所作之修 飾或等效變化，仍應包括本案申請專利範圍内。 201217042 【圖式簡單說明】 第一圖係習知有機溶劑淨化裝置之結構說明圖。 第二圖係活性碳之吸附性能說明圖。 第三圖係本發明第一實施例之結構說明圖。 第四圖係本發明第二實施例之結構說明圖。 【主要元件符號說明】 (ίο)活性碳吸脫附裝置 (20)淨化裝置 (30) 熱交換器 (31) 控制器 (40) 洗滌器 (41) 冷卻器 (50)熱泵201217042 VI. Description of the Invention: [Technical Field] The present invention relates to an organic solvent purification device, and more particularly to an exhaust gas to be purified which contains an organic solvent generated by a process, and first removes particles in the exhaust gas flow by using ice water. The designer of the adsorption process is cleaned and dehumidified, then heated moderately by a heat exchanger, and then activated by an activated carbon adsorption and desorption device. [Prior Art] Organic solvents widely used in life and production are highly volatile at room temperature, so they are also known as Volatile Organic Compounds (VOCs), and most VOCs are toxic to humans. It must be treated; however, for the VOCs generated by the process (such as the spraying process), the VOCs are adsorbed and concentrated by an activated carbon adsorption and desorption device (10) as shown in the first figure. In the desorption process, the purified VOCs are incinerated or recovered by a purification device (20). According to the second press, the adsorption performance of activated carbon is as shown in the second figure. The adsorption capacity of VOCs is opposite to that of water absorption. When the relative humidity is low, the adsorption capacity for VOCs is high and the water absorption capacity is poor. When the relative humidity is high, the water absorption is high. High capacity and poor adsorption capacity for VOCs, and its adsorption performance will change rapidly in the transition range of relative humidity 50~60%RH; therefore, the above-mentioned conventional organic solvent purification device enters the activated carbon adsorption and desorption device in the exhaust gas flow ( 10) At the same time, since the relative humidity of the exhaust gas stream is easily affected by the weather, the ability of the activated carbon adsorption and desorption device (10) to adsorb VOCs is unstable, that is, the overall purification effect is unstable. Press again, there are usually micro 201217042 particles that cannot be filtered by the filter in the exhaust gas stream, and these particles will block the pores of the activated carbon, reduce the adsorption of activated carbon, and once the particles are blocked by activated carbon It is difficult to remove after the hole, and the service life of the activated carbon is shortened. SUMMARY OF THE INVENTION The main object of the present invention is to solve the problem that the prior art is susceptible to weather and the effect of purification is unstable, and the effect of purifying the effect is not affected by the weather. Another object of the invention is to have the effect of extending the useful life of the activated carbon. Another object of the present invention is to have an energy saving effect. In order to achieve the above effects, the structural feature of the present invention is that a waste gas to be purified containing an organic solvent generated by the process is introduced into an activated carbon adsorption and desorption device, and a purification device is disposed at a downstream end of the activated carbon adsorption and desorption device. A heat exchanger for raising the temperature is disposed at the upstream end of the activated carbon adsorption and desorption device. Further, a scrubber is further provided at the upstream end of the heat exchanger. Further, a cooler is further provided to cool the washing water of the scrubber. In addition, a heat pump is connected to the heat exchanger to connect the heat exchanger to the cooler, and the heat exchanger and the cooler are respectively heat-exchanged with the condenser and the evaporator of the heat pump. Further, the heat exchanger further adjusts the temperature rise by a controller, and the controller adjusts the temperature rise of the heat exchanger according to the relative humidity (or dew point temperature) of the exhaust gas to be purified. Further, the heat exchanger causes the relative humidity of the exhaust gas to be purified introduced into the activated carbon absorption and desorption device to be maintained below 6〇% RH. In addition, the activated carbon adsorption and desorption device is an activated carbon fluidized concentration 201217042 or a solid bed type concentrator. Further, the purification device is an incinerator, a condenser, a spray chamber or a spray plus ozone chamber. [Embodiment] First, referring to the third embodiment, the first embodiment of the present invention is a process for producing an exhaust gas-inducing carbon-desorption device (ίο) containing an organic solvent, which is treated by (4). Purifying the organic solvent in the exhaust gas for adsorption and concentration desorption, and the activated carbon adsorption and desorption device (1〇) may be an activated carbon fluidized concentrator or a fixed bed concentrator; A purification device (20) is disposed at the downstream end of the attachment device (10), and the organic solvent concentrated and desorbed by the activated carbon adsorption and desorption device (丨〇) is subjected to purification treatment by incinerator incineration or condenser recovery. Further, a heat exchanger (3〇) for raising the temperature is disposed at an upstream end of the activated carbon adsorption and desorption device (10), and the exhaust gas to be purified introduced into the activated carbon adsorption and desorption device (10) is appropriately heated. By referring to the hygrometer, it is clear that the result of the temperature rise causes the relative humidity to decrease, that is, the setting of the heat exchanger (30) can enhance the adsorption capacity of the activated carbon adsorption and desorption device (10) to the organic solvent. In addition, the heat exchanger (30) is further regulated by a controller (31), and the controller (31) adjusts the heat exchanger according to the temperature and relative humidity (or dew point temperature) of the exhaust gas to be purified. The degree of temperature rise of (3〇) is such that the relative humidity of the exhaust gas to be purified introduced into the activated carbon adsorption and desorption device (1〇) is maintained below 60% RH. Furthermore, referring to the fourth embodiment, the second embodiment of the present invention adds a scrubber (40) to the first embodiment, and the scrubber (40) is disposed at the upstream end of the heat exchanger (30). For filtering the particles in the exhaust gas stream; however, if a cooler (41) is further provided to cool the washing water, the 201217042 scrubber (40) can further reduce the dew point temperature of the exhaust gas stream, thereby generating dehumidification. Therefore, since the heat exchanger (3〇) must consume heat energy, and the cooler (41) must dissipate heat energy, the heat exchanger (50) is coupled to the cooler (41) by a heat pump (50). The heat exchanger (30) and the cooler (41) are respectively exchanged with the condenser of the heat pump (5〇) and the evaporator, and the heat energy that must be dissipated by the cooler (41) is converted into the heat exchanger. The heat energy that must be consumed by the heat exchanger (30), and thus the energy saving; and the operating state and composition of the heat pump (5 〇) are not patents of the present invention and will not be described again. Based on the composition of the present invention, the present invention is directed to a waste gas to be purified containing an organic solvent produced by the process, and the particulates in the exhaust gas flow are first filtered out by the scrubber (4〇), and dehumidification can be performed first if washing with ice water. Then, the heat exchanger (30) is moderately heated (usually not more than 45. 〇, 俾, the relative humidity is maintained below 60% RH, so that the activated carbon adsorption and desorption device (1 〇) in the adsorption capacity of activated carbon In the preferred environment, the adsorption process is not affected by the weather, and the purification effect is unstable, and the entanglement of the activated carbon pores by the particles is reduced. Therefore, the present invention has the effect of purifying the stability without being affected by the weather and prolonging the activated carbon. The effect of the service life.
